Page "Eiríkr Hákonarson" Paragraph 7

Hákon Sigurðarson was a strong believer in the Old Norse gods, and when Harald Bluetooth attempted to force Christianity upon him, Haakon broke his allegiance to Denmark.

A Danish invasion force was defeated at the battle of Hjörungavágr in 986.

According to Heimskringla, Eric, apparently reconciled with his father, commanded 60 ships in the battle and emerged victorious.

After the battle he gave quarter to many of the Jomsvikings, including Vagn Ákason.
